gene therapy in treating patients with unresectable, recurrent, or refractory head and neck cancer

Conditions: Head and Neck Cancer

Summary: participant with squamous cell cancer of head and neck are invited to participate in this study. in this study the investigators will be inserting the gene for interleukin-12 into a person's cancer cells with the anticipation to make the body build an immune response to kill more tumor cells.

this is a phase i/ii trial to study the effectiveness of gene therapy in treating patients who have unresectable, recurrent, or refractory head and neck cancer.
